NethServer Version: 7.9.2009 (final)
Module: Nextcloud
when trying to access my Nextcloud I just get a error Message:

Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

I want to use Nextcloud as a virtual host.
when trying to add the hostname to the let’s encrypt certificate I get also an error message.

I had nexcloud running without a problem for a while with a few users. since no one neddet it I ignored the error when the Let’s encryt certificate could not update. Looks like there something complete brocken, I tried to reinstall, did’nt work eiter.

systemctl -l status rh-php73-php-fpm
3

php
php704×503 11.4 KB

And mysqld?

systemctl -l status mysqld
5

is not working

 systemctl -l status mysqld

First things first. Can you give some more info about your NethServer and Nexcloud install?

  • is your server directly connected to the internet?
  • did nextcloud ever ‘work’ as expected?
  • on what (sub)domain is/should be your nextcloud accessible?
  • is the (sub)domain correctly registered in public DNS?
7

If there is no other service/process using the socket you can try renaming the socket file and starting the mysqld service.

lsof /var/lib/mysql/mysql.sock        # check which process is using the file (if any)
mv /var/lib/mysql/mysql.sock{,.bak}   # rename the socket file
systemctl start mysqld
8

there was another process mysqld running. after I killed it, now mysql is up

systemctl -l status mysqld

on the nextcloud virtual host

It appears to be:

dan@Dan-MacBook-Pro-2013  ~  host nextcloud.nemenz.at
nextcloud.nemenz.at is an alias for home.nemenz.at.
home.nemenz.at has address 178.115.248.17

There should be an error logged somewhere, either in one of the Apache log files or in /var/log/messages. Without that, we’re just guessing.

It seems you have an old version of Nextcloud installed where rh-php72 is used:

systemctl -l status rh-php72-php-fpm

Updating your server should solve the problem.

intresting. I checked the Updates earlier today, there where none. now there where 44.
Still not working…

14

Just to be sure, let’s check the Neth version:

cat /etc/nethserver-release

You may start the service to check if it makes Nextcloud work:

systemctl start rh-php72-php-fpm

Do you use custom templates for Nextcloud?

cat /etc/nethserver-release
NethServer release 7.9.2009 (final)

I dont think so

After startuing the php stack, nextcloud cam up with this message:
Exception: Updates between multiple major versions and downgrades are unsupported.

16

See this wiki article for solving this issue.

after a reboot I need to start php7.2 again on the terminal. How can I start it automatical?

19

You can enable it with

config setprop rh-php72-php-fpm status enabled

to start automatically.

But rh-php72 shouldn’t be needed by Nextcloud in recent versions.

Let’s check the nextcloud version:

rpm -q nethserver-nextcloud

Is it nethserver-nextcloud-1.16.6-1 ?

20

it is

rpm -q nethserver-nextcloud
nethserver-nextcloud-1.16.6-1.ns7.noarch
